A report card is like a special piece of paper that tells you how well you're doing in school. You get it a few times during the year, and your teachers fill it out with information about what you've learned and how you're doing in different subjects like math, reading, and science.
The report card might have some letters like A, B, C, D, or F. These letters tell you how good you're doing in each subject. An A means that you're doing really well, a B means you're doing pretty good, a C means you're doing okay, a D means you're not doing very well, and an F means you need to work harder.
But the report card is not just about grades. It might also have some comments from your teachers about why you got the grades you did. They might also tell you some things that you did well or some things you need to work on.
Parents will usually look at your report card and talk to you about it. They might help you figure out what you need to do to get better grades or praise you for doing a good job. So, report cards are a way to see how well you're doing in school and help you improve if you need to.
